Scope and Claims Analysis of U.S. Patent 9,610,260
What Does U.S. Patent 9,610,260 Cover?
U.S. Patent 9,610,260, granted on April 4, 2017, is titled "Methods of Treating or Preventing Diseases with Selective Estrogen Receptor Modulators (SERMs)." The patent protects specific methods of using SERMs to treat various medical conditions. Its claimed inventions focus on methods of administering particular chemical entities to achieve desired therapeutic effects, including hormone-responsive diseases.
Patent Scope
The patent covers:
- Methods of treatment: Administration of specific SERM compounds in defined regimens to treat or prevent diseases such as breast cancer, osteoporosis, and related disorders.
- Therapeutic applications: Use of claimed compounds for estrogen receptor modulation in both estrogen receptor-positive and -negative conditions.
- Dosage and formulations: Specific dosing schedules, compositions, and routes of administration tailored to the compounds.
- Chemical entities: The patent claims include a class of compounds with particular structural features, primarily based on substituted tamoxifen analogs.
The claims extend to both pharmaceutical compositions and methods of treatment involving these compounds. The scope emphasizes selectivity in receptor binding and specific therapeutic indications.
Key Claims Breakdown
The patent contains 20 claims; the most relevant include:
- Claim 1: A method of treating a disease or disorder, comprising administering to a subject a therapeutically effective amount of a compound of formula I, where formula I encompasses a class of substituted tamoxifen derivatives with specific chemical substitutions.
- Claim 2: The method of claim 1, wherein the disease is breast cancer.
- Claim 4: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 10: The method of claim 1, wherein the compound is administered orally.
- Claim 15: The compound of formula I where specific substituents are defined, such as halogens or alkyl groups at particular positions, providing chemical specificity.
Claims focus on both the chemical compounds and their methods of use, with particular attention to dosage, formulations, and indications.
Patent Landscape
Related Patents and Applications
-
Prior Art: The patent cites prior patents and publications related to SERMs, tamoxifen derivatives, and selective estrogen receptor modulators.
-
Patents Expanding the Patent Family:
- Several international filings (e.g., WO applications) extend the patent rights.
- Related patents include U.S. patents on other chemical variants and treatment methods for estrogen receptor-related disorders.
Competitor Patents and Overlaps
- Patents filed by companies such as Eli Lilly, AstraZeneca, and Pfizer cover similar SERM compounds and indications.
- Overlap exists in the chemical scaffold—particularly tamoxifen analogs—and their therapeutic uses.
- Competitor patents tend to focus on chemical modifications that improve selectivity, reduce side effects, or extend patent life.
Patentability and Freedom-to-Operate (FTO)
- The patent claims are directed onto specific chemical modifications with demonstrated therapeutic effects.
- The scope appears sufficiently narrow to avoid initial invalidity but overlaps with existing tamoxifen-related patents require careful FTO analysis.
- The claims' specificity on administration regimens and chemical structure helps in avoiding prior art but limits broad claims.
Patent Life Cycle and Term
- Filing date likely around 2014; expected expiration around 2034, accounting for patent term adjustments based on U.S. patent law.
- Patents in this class often face challenges from generic companies after 20 years post-filing.
Implications for R&D and Commercialization
- The patent provides exclusivity over specific derivatives and treatment methods.
- Its broad chemical scope secures rights across multiple indications.
- Limited claims on formulations could allow competitors to develop alternative delivery methods or different chemical modifications.
Key Takeaways
- U.S. Patent 9,610,260 protects specific tamoxifen derivatives for treating estrogen receptor-related diseases.
- Claims focus on chemical structures, methods of treatment, administration routes, and dosages.
- The patent landscape includes overlapping rights on SERMs, with potential challenges from prior patents.
- The patent's lifetime extends into the mid-2030s, offering long-term exclusivity.
- Any competitor planning to develop similar compounds must navigate the narrow scope of claims and existing patent landscape.
